A new class, DDMathOperatorSet, defines a collection of operators. There is a “default” instance, but you can allocate your own instances to customize the sets of operators used in different contexts. This has several side effects:
- The interpretation of “%” as either percent or modulo can now be customized at runtime instead of compiletime
- Tokenization can be much more lenient in what characters are allowed in function names
